Urban habitat fragmentation and floral resources shape the occurrence of gut parasites in two bumblebee species

open access: yesEcology and Evolution, Volume 13, Issue 7, July 2023., 2023
Urbanization and the expansion of human activities foster radical ecosystem changes with cascading effects also involving host‐pathogen interactions. Urban pollinator insects face several stressors related to landscape and local scale features such as green habitat loss, fragmentation and availability reduction of floral resources with unpredictable ...

Bumble bee colony health and performance vary widely across the urban ecosystem

open access: yesJournal of Animal Ecology, Volume 91, Issue 10, Page 2135-2148, October 2022., 2022
Urbanization can affect species diversity. Yet, whether urbanization affects fitness remains largely neglected. This experiment using bumblebee colonies reveals strong relationships between temperature and landscape‐scale drivers and colony health, performance and reproductive success, suggesting that environmental heterogeneity within the urban ...

Assessment of intestinal parasites in the coexisting Bombus terrestris (Apidae) and Xylocopa augusti (Apidae) in central Chile

open access: yesRevista Chilena de Historia Natural, 2020
Bombus terrestris is a European bumblebee extensively commercialized worldwide for crop pollination. In Chile, this species was introduced in 1997 and after confinement escape, it has spread and established in several localities of central-southern Chile

The puzzle of monarch butterflies (Danaus plexippus) and their association with plants containing pyrrolizidine alkaloids

open access: yesEcological Entomology, Volume 46, Issue 5, Page 999-1005, October 2021., 2021
1. The chemical defences of monarch butterflies involve two kinds of secondary plant metabolites: cardiac glycosides (CGs) that are obtained from larval hostplants, and pyrrolizidine alkaloids (PAs) that are gathered by adults usually independent from feeding behaviour.

Morphological characteristics of local entomopathogenic protozoan strains isolated from insect cadavers of certain stored-grain pests in Egypt

open access: yesEgyptian Journal of Biological Pest Control, 2020
The present study has documented, for the first time in Egypt, the natural occurrence of four entomopathogenic protozoans (EPP) among five of the most abundant and damaging insect pests of stored grains or their products. These insect pests (Laemophloeus

First record of the entomopathogenic protist, Mattesia dispora (Neogregarinorida: Lipotrophidae) of the Mediterranean flour moth, Ephestia kuehniella Zeller (Lepidoptera: Pyralidae) in Turkey

open access: yesEgyptian Journal of Biological Pest Control, 2019
The present study is the first record of a natural neogregarine infection of Ephestia kuehniella Zeller (Lepidoptera: Pyralidae) in Turkey. The infection occurs in the fat body and hemolymph of the larvae.

Positive‐Strand RNA Viruses Infecting the Red Imported Fire Ant, Solenopsis invicta

open access: yesPsyche: A Journal of Entomology, Volume 2012, Issue 1, 2012., 2012
The imported fire ants, Solenopsis invicta and S. richteri were introduced into the USA between 1918 and 1945. Since that time, they have expanded their USA range to include some 138 million hectares. Their introduction has had significant economic consequences with costs associated with damage and control efforts estimated at 6 billion dollars ...

Museum collections reveal a global range of Ophryocystis parasites in Danaus butterflies

open access: yesEcological Entomology, Volume 50, Issue 3, Page 552-564, June 2025.
We analysed 2727 museum specimens from 61 butterfly species across 86 countries to document the occurrence and host range of Ophryocystis elektroscirrha (OE) and related parasites in milkweed butterflies. Ophryocystis parasites infected Danaus petilia (16%), D. plexippus (12%), D. chrysippus (11%), D. gilippus (4%) and D.

Answering key bumble bee conservation questions by studying discovered wild nests: A Bombus affinis case study

open access: yesInsect Conservation and Diversity, Volume 18, Issue 3, Page 303-318, May 2025.
The information learned from discovered wild bumble bee nests can be of great conservation value if studied in situ and post‐season excavation in a standardised way. We provide standardised guidance to follow when nest discoveries arise, including key conservation questions and methodological guidelines to study behaviour, floral use, genetics, body ...
